FYI, you could have taught me instead of mocking my lack of knowledge. I didn't come here for that. I came to learn.

No. It just means that you did not complete the circuit. Infinity means that you have a completed circuit, or more resistance than the meter is able to tell you.

Nobody is mocking anyone. I have stated this before for others. I tend to anymore just lay it out on the table and tell it like it is, other than sugarcoating like some, or trying to play guessing games, or play who is bigger than the person coming for help. Sort of like some that have the David & Goliath complex.

"That is a first. Never knew that you could use resistance to figure out a ac electrical circuit."

Come on, you know very well that this a perfect example of sarcasm. I don't really care to argue over the fact, but as someone who came here to seek knowledge, I really didn't appreciate the comment. You could have just explained it as you did in a later post. Your constructive comments are appreciated though.

Yes, that is correct.

No, that is not sarcasm. You can not use resistance to figure out a electrical circuit. There is a correct way of doing things, and as I have already stated over and over, a wrong way or a way of over thinking things like most people on the Internet tend to do, when posting on BBS type forums. Anymore, it is starting to appear that most that post out on the Internet asking questions, but over thinking problems, just need to stop and use K.I.S.S process.

I myself tend to over think stuff, but I get paid to think outside of the box for a living, same when I was in the Navy solving a majority of the issues that others would not fix. I could get the problem resolved and move on to the next job.

If you two are through arguing then think about this:
Resistance is a measurement where continuity is a condition.

a7, across from, next to, if your breaker box is 120x2, then 240 can be found between any two points, that was my point.
greg, yes, explanation kinda confusing, how many megs are code now?.
trv, continuity and resistance are similar in concept. Zero resistance = full continuity. Using a normal meter uses dc current. What we are looking at is ac. Never use your meter to calculate anything. These tests only suggest anwsers, not prove them. Think of a massive long water pipe that you cap on both ends, then add a little water pressure thru one side and measure the resultant pressure on the other. All you can deduce is that both ends are connected, not the volume of water that can flow thru the pipe.

Two types of volt meters, analog and digital, both have strenghts and weaknesses
Analog Plus:

Perfect to test caps
Good for absolute testing

Analog minus:
Gotta pay attention

Digital Plus:
can measure anything with a super high internal resistance (impedance)
Little skill required

Digital minus:
The super high internal resistance can't even "bleed off" radio or earths magnetism. If you don't believe me wave your test leads, you'll drive it crazy, auto range flying, readings over 1 volt from nothing.

Connect one lead to a live wire, leave the other free(the free lead will possess the voltage of the live one) and its no telling what the display will reveal.

Can you explain the analog pluses?

Greg.,

The other common term for MegOhm is Megger and I used pretty often over my area ( In France ) so I can able weed out bad cables espcally with older BX it will fail useally found in junction boxes that is the most common place I will find it but from time to time middle of run it will show up as well.

Merci,
Marc

"Absolute" kinda a silly word, I just meant there is no auto ranging so you can't miss the unit display, missing m or k or M can have serious consequences.

Test Caps, sure, not for their capacitance value but for good/bad, pass/fail type test.
